它们是静态的嵌套类。
您可以使用以下方式引用它们：
OuterClass.StaticNestedClass nestedObject =
new OuterClass.StaticNestedClass();
内部类不是静态的，与其封闭类的实例相关联：
OuterClass outerObject = new OuterClass()
OuterClass.InnerClass innerObject = outerObject.new InnerClass();
英文:
They are static nested classes.
You can reference them using:
OuterClass.StaticNestedClass nestedObject =
new OuterClass.StaticNestedClass();
The inner classes are not static and are associated with an instance of its enclosing class:
OuterClass outerObject = new OuterClass()
OuterClass.InnerClass innerObject = outerObject.new InnerClass();
